<br />LIST OF TABLES (Continued) <br />Table Page ~ <br />9. Characteristics of habitats seined during spring inci- <br />dental seining and fall standardized YOY seining, San <br />Juan River, Utah. For temperature data (Temp) BA = <br />backwater and MC =main channel. Also presented are <br />the number of rare species collected (CS = Colorado _ ~ <br />squawfish; CH = chubs in the genus Gila), and total <br />lengths of Colorado squawfish collected. 26 <br />10. Total number collected percent species composition <br />(%), and mean catch-per-unit-effort (CPUE, fish/100 <br />m2) of fishes in backwaters of the San Juan River, ~ <br />Utah. Data collected by UDWR and BOR are presented <br />separately for respective areas of the river sampled. 30 <br />11. Mean catch-per-unit-effort (CPUE, fish/100 m2) in <br />1987 of three exotics in backwaters in the Colorado, <br />Green and San Juan rivers. Data for the Colorado ~ <br />and Green rivers is from the Interagency Standardized <br />Monitoring Program, U.S. Fish and Wildlife Service, - <br />Colorado River Fishery Project, Grand Junction, <br />Colorado. 31 <br />12. Total number collected, % species composition (%~, ~ <br />and mean catch-per-unit-effort (CPUE, fish/100 m ) <br />for selected species from backwaters of the San Juan <br />River, Utah September 9-13, 1987 by three geomor- <br />phologic areas of the river. Calculations are <br />based on the first seine hauls of backwaters; % <br />values were calculated using the total number of ~ <br />fishes seined in each geomorphologic area. Total <br />fishes seined in 4-Corners to Sand Isl. = 2227; Sand <br />Isl. to Mex. Hat = 28; Mex. Hat to Grand Gulch = 99. 32 <br />13. Total number collected and percent composition (%) <br />for selected species from backwaters of the San ~ <br />Juan River, Utah, sampled October 15-17, 1985. <br />Percent composition of respective species were <br />calculated using the total number of fishes <br />seined in each geomorphologic area. Total fishes <br />seined in Aneth to Sand Isl. = 1790; Sand Isl. <br />to Mex. Hat = 469. 34 ~ <br />14. Gill and trammel net catches during spring, March <br />18-April 12, 1987 and fall, September 18-27, 1987 <br />from the San Juan Arm of Lake Powell. 35 <br /> <br />iii ~ <br />
